摘要目的探讨DR双能量减影技术在急诊胸腹部外伤诊断中的应用价值。方法对我院收治的75例肋骨骨折（共159处）、60例气胸、45例膈下游离气体患者进行双能量减影检查，并与患者的标准DR片进行对比分析。结果标准DR检出骨折135处，气胸50例，膈下游离气体30例，检出率分别为84.9%、83.3%、66.7%；双能量减影检出骨折150处，气胸60例，膈下游离气体43例，检出率分别为94.3%、100%、95.6%，双能量减影的病变检出率明显高于标准DR。结论双能量减影技术可清晰显示肋骨骨折、少量气胸、肺内小结节和腹部少量游离气体等病变，对胸腹部急诊外伤具有较高的诊断准确率，值得推广应用。

Abstract：Objective To investigate the effectiveness of application of DES-DR (Dual-Energy Subtraction Digital Radiography) technique in diagnosis of chest and abdominal emergency trauma. Methods DES was performed in 75 patients with 159 rib fractures, 60 pneumothorax patients and 45 subphrenic free gas patients so as to compare and analyze the results with standard DR images. Results The standard DR images showed 135 cases of fractures, 50 cases of pneumothorax and 30 cases of subphrenic free gas with the detection rates 84.9%, 83.3 % and 66.7% respectively. The DES images revealed 150 cases of fractures, 60 cases of pneumothorax and 42 cases of subphrenic free gas with the detection rates 94.3%, 100% and 95.6% respectively. Obviously higher detection rates were achieved through DES than standard DR. Conclusion DES-DR could clearly show lesions including the rib fractures, slight pneumothorax, small pulmonary nodules and a small amount of abdominal free gas, which realized the high diagnosis rate of chest and abdomen emergency trauma and deserved wider clinical promotion.

Key words： dual energy subtraction standard digital radiography chest and abdominal trauma detection rates
